Can anyone please confirm which escalators are out of service for refurbishment at Kings Cross, and is the one-way system sending people from westbound sub-surface towards the exit at the rear of the train or the exit at the front of the train?
The sign I noticed at Kings Cross when I passed through just over a week ago said it would be the escalators leading down to the Piccadilly & Northern lines from the 'tube ticket hall' (Euston Road exit side).
From this I'd imagine they'd be sending people towards the front of the westbound sub-surface platform as otherwise they would be sending people towards where the escalator work is, but perhaps someone else should confirm for certain.
4, 5, 6 - i.e. the Piccadilly line escalators from the Tube dateline to the Piccadilly concourse. The ones where the fire was is probably the, err, easiest way to explain them.
The Tube gate line is operating as exit-only, but the Khyber pass (from the Met platforms to the Tube gate line) remains open in both directions for interchange. Access to the Victoria line (and, as such, the 'dog leg' from the Victoria line concourse down to the top of escalators 1, 2, 3 for the Northern line) remains available as usual. Officially, all entry to the deep level lines is via the Northern ticket hall, but those in the know may be able to avail themselves of the above suggestions (usual caveats apply regarding additional station control measures!). Remember, of course, there's also the Pentonville Road entrance, which is generally unaffected by control measures when open. Perhaps a slightly longer walk, but you'll likely have a more comfortable passage to get to the trains.
